GAS-LlGHT-FLASHING DEVICE.

SPECIFICATION forming part of Letters Patent No. 773,897, dated November 1, 1904.

Application filed June 18, 1904. 'Serial No. 213,118. No model.)

ond, to provide a device which may be 10- cated in any convenient place not necessarily near the burners to be flashed; third, to provide a device wherein the rising and fallingof a liquid-level closes and opens a valve leading to the burners to be flashed; fourth, to provide a device which can be easily manufactured and adjusted, and other objects which will further appear in these specifications.

The principles of our invention are clearly pointed out in the claims hereto, and a structure showing the same may be seen in the accompanying drawings, in which Figure 1 is a plan view of our device without the burners. Fig. 2 is a side elevation of aportion of the reservoir and the safety stand-pipe of our device. Fig. 3 is a side sectional view of the float-chamber and reservoir of our device upon line A B of Fig. 1, exposing to view the working parts of our device. Fig. 4: shows a gas-burner of ordinary pattern with its pilot-burner near by. Fig. 5 is a detail view of the valve, the opening and closing of which produces the flashing at the burner or burners.

Similar letters of reference refer to like parts throughout the several illustrations.

(6 is a cap which fits the float-chamber m and is secured thereto by means of screws or Through this cap 0 passes the gas-intake pipe 6, the gas entering in the direction of the arrow shown at the bottom of said intake. This cap CZ also carries the outlet-pipe (Z and the pivot m or support for the valve-lever 0 and the support '11 for guiding the float-stem j of the float F.

pended upon a threaded rod carrying the finger-p1ece e and passing through a bushing in the top of said reservoir, as shown in Fig. 3.

In the float-chamber is placed a non-evaporative liquid, (indicated as E, Fig. 3,)upon the surface of which rests the float F, with the upwardly-extending stem j. The gas entering the intake Z under pressure forces this liquid up through the connecting-pipe t and into the reservoir 1, as shown in Fig. 3.

Fig. 5 shows a detail view of our main operating-valve m, being the support above referred to and 0 the lever carrying the disk n. A sectional view of a portion of this lever 0 shows the manner in'which we seat this disk 02 upon the lever 0, the object being to give the disk 12 a certain amount of freedom when the same comes in contact with the opening in the outlet-pipe (Z. Upon one end of the lever '0 is the weight 9, which serves to a certain extent to counterbalance the portion of the lever carrying the disk a. it and 7d are the contact disks upon the stem above referred to and which open and close the valve shown in Fig. 5, as hereinafter described. From the outlet-pipe (Z to the burner (Z is a pipe connection of any kind and also such pipe connection between the pilot-burner Z) and the gas-intake pipe 6, or the gas-main itself, if more convenient. In the outlet-pipe (Z we have placed a needle-valve cof ordinary pattern, Fig. 3, with an upwardly-extending adjusting-screw c. In case it is not desired to use the pilot-burner b a slight opening may be left by virtue of said needle-valve c in said outlet-pipe (Z. Thus when the valve 91 closes the said opening in said outlet-pipe (Z the light will not be turned entirely out, but merely to a point where it cannot be readily seen.

At the bottom of Fig. 3 will be seen the safety check-valve 7/, which is operated by the small float F. The object of this valve is to prevent the escape of gas from the float-chamber in case of a stoppage in the outlet-pipe (Z or burner (1 for any cause, in which case the pressure in the gas-main would continue to reservoir g. By reason of this safety-valve u and its float F if the liquid in this floatchamber be lowered abnormally for any reason this valve it closes, thus preventing the gas from entering the pipe t. As an additional safety device We have provided the .stand-pipef', which extends upwardly from the reservoir. The fluid-space in the floatchamber being greater than the area in the reservoir, in case of a stoppage, as above described, after filling the reservoir the liquid would be forced upwardly into the stand-pipe, which may be of suflicient height to cause head enough when so filled to counterbalance the pressure in the gas-main, and thus prevent any further flow of gas. In the upper portion of this stand-pipe will be seen a small opening through which the air can pass as the liquid-level changes in the operation of the device.

The operation of our device is as follows: The gas entering the intake-pipe fills the space in the float-chamber .7 (indicated as G.) By reason of its pressure this gas forces the liquid E in said float-chamber down and up through the pipe 6 and into the reservoir r This allows the float F to fall with the liquid until the disk It contacts with the spring Z with sufficient force to cause the valve 71/ to drop away from the opening in the outlet-pipe (Z or to position as shown in Fig. 5. \Vhen this action takes place, the gas rushes out through the outlet-pipe (Z to the burner (Z, and the light flashes up to its full height. This relieves the pressure to a certain extent in the gas-chamber or space, (indicated as (i and the liquid, owing to the head, it has just acquired, accordingly rises in the float-chamber m until the valve 12 again closes the opening in the outletpipe (Z, and the light at the tip 7' of the burner (Z is extinguished; The frequency with which the operation occurs depends upon the adjustment of the valve 7), which limits the flow of liquid through the pipe t. The object of the springs Z and l is to produce a sudden opening and give a better action to the valve.

Our invention will admit of many variations; but
